Common Name

(2s,6s,8as)-2-[(1s,2r,3r)-3-[(2r,3e,5r)-5,6-dimethylhept-3-en-2-yl]-2-(2-hydroxyethyl)-2-methylcyclopentyl]-6-hydroxy-8a-methyl-2,3,5,6,7,8-hexahydronaphthalen-1-one

Description

Leptosterol A belongs to the class of organic compounds known as ergostane steroids. These are steroids with a structure based on the ergostane skeleton, which arises from the methylation of cholestane at the 24-position. (2s,6s,8as)-2-[(1s,2r,3r)-3-[(2r,3e,5r)-5,6-dimethylhept-3-en-2-yl]-2-(2-hydroxyethyl)-2-methylcyclopentyl]-6-hydroxy-8a-methyl-2,3,5,6,7,8-hexahydronaphthalen-1-one is found in Sinularia leptoclados. Based on a literature review very few articles have been published on Leptosterol A.
